general problems of the 2022 Chevrolet Silverado 2500

My 2022 Chevrolet Silverado 2500hd high country 6. 6l duramax engine has an exhaust leak that causes diesel exhaust to travel into the pickup's cab through the outside air vent and air conditioning system during the exhaust system's regeneration. This occurs when the regeneration occurs in city driving especially at low speeds, stop lights, stop signs, parking lots, etc. The pickup has been to the dealer to find and make necessary repairs twice and is currently at the dealer's shop for the third time. This issue with the 6. 6l duramax pickups appears to be a common theme amongst owners and gm should be providing dealers with the appropriate fix with a recall of the exhaust system. This is a safety hazard as carbon monoxide enters the cab with the diesel exhaust and must be rectified. On my pickup, this started at approximately 55,000 miles. Thank you for your prompt attention to this serious air quality issue inside the pickups' cabs.

While driving on the freeway in a construction zone, I smelled a burning oil smell. I considered the possibility it was in relation to road repairs being done (roads being repaved, ie tar resurfacing). I was cut off by another vehicle and depressed my brakes and I saw a poof of smoke over the front passenger area near tire. I noticed all of my gauges were in the normal ranges (temperature, battery voltage, etc. ) in less than a minute my truck went into limp mode and advised it had a def system issue and it would be limited to a set mph and a set number of miles. Check engine light came on and another driver alerted me that the underneath of my vehicle was on fire. I pulled over to the side of the highway and my truck became engulfed in flames in. Truck is under factory warranty, unmodified, never been in an accident and has had all recommended services performed at local dealership. There was a significant amount of traffic and luckily I did not collide with anyone or set neighboring dry grass field on fire. Fire department responded and extinguished the fire, but it is a total loss. Insurance company has been notified, and vehicle will be available for inspection by appropriate agencies. While local law enforcement did respond, they did not take a report because I didn't hit anything, and the only property damage was my own. (there is documentation of the event, but just dispatch notes. ) prior to the situation above the truck had been at operating temperature for at least 20 minutes and I had traveled for about 20 miles on the highway. The total distance traveled from when I smelled the burning smell was maybe 1. 5 miles.

See attached document for complaint.

I was almost run over by a semi-truck when entering the freeway because my 2022 Chevrolet truck would not accelerate. I was told at the dealer the loss of power was intentionally caused by the onboard computer. It is programed by the manufacturer to do this anytime certain repairs may be needed. In my case, the life-threatening event I experienced took place because a sensor went out and the computer thought a repair was needed.

The contact owns a 2022 Chevrolet Silverado 2500. The contact stated that on four occasions while driving at various speeds with the accelerator pedal depressed, the vehicle inadvertently slowed down and failed to exceed 50 mph. The check emissions warning light was illuminated. The vehicle was taken to a dealer but was not diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was 16,980.
